140: Send a *WA1 command to the source. This command
causes the source to stop executing new commands until all prior
commands and operations have completed execution. In this case,
there is a sweep in progress, so no further commands will be
executed until the sweep finishes.
150: Turn the RF output of the source ON.
160: Initiate a sweep on the source.
170: Send another *WA1 to the source. Although the *WA1
command causes EXECUTION of commands to be held off, it
has no effect on the transfer of commands over the HP-IB. The
commands continue to be accepted by the source and are buffered
until they can be executed.
180: Toggle the RF STATE to OFF.
190: Repeat the sample exercise.
200 and 210: Print messages on the computer display.
